The clothes receptacle provided in the cabinet 1 may include a tub 2 in which wash water is stored, and a drum 3 rotatably installed in the tub to store laundry.

The tub 2 is provided in a cylindrical shape and fixed to the inside of the cabinet 1 by a tub supporting portion 21. The tub 2 is provided with a tub inlet 22 communicating with the inlet 13 on the front side.

A gasket 23 is provided between the tub inlet 22 and the inlet 13 so that the gasket 23 prevents the vibration generated in the tub 2 from being transmitted to the cabinet 1, It is preferable to use an elastic material such as rubber to prevent the washing water stored in the washing water from leaking.

The drum 3 is rotatably supported inside the tub 2 by a driving part M provided on the rear surface of the tub 2 and includes a drum inlet 31 communicating with the tub inlet 22, And a through hole (33) provided to penetrate the circumferential surface of the drum (3).

The circulating duct 7 may be provided on the upper circumferential surface of the tub 2 for drawing the air inside the tub 2 out of the tub 2 and guiding the air to the tub 2 again.

The tub 2 may be provided with a first communicating part 26 and a second communicating part 27 for coupling with the circulating duct 7.

2, the first communicating portion 26 is a flow path for guiding the air inside the tub 2 to the circulating duct 7, and the second communicating portion 27 flows into the circulating duct 7 And the air is guided to the tub 2 by the air.

The second communicating portion 27 may be provided in the gasket 23. That is, the second communicating portion 27 is provided with a hole penetrating the gasket 23, and the air outlet of the circulating duct 7 can be coupled to the hole formed in the gasket 23.

The second communicating portion 27 may be provided on the circumferential surface of the tub as in the first communicating portion 26. When the second communicating portion 27 is provided in the gasket 27, The air can be supplied to the central portion of the drum 3 through the drum inlet 31, which is advantageous for increasing the heat exchange efficiency between the laundry and the air.

The heating unit provided to supply the heated air to the tub 2 may be provided with a fan 71 and a heater 73 provided in the circulation duct 7. The fan 71 not only allows the air inside the tub 2 to flow into the circulating duct 7 through the first communicating portion 26 but also causes the air introduced into the circulating duct 7 to flow into the second communicating portion 27 And the heater 73 is means for heating the air moving to the second communication portion 27 through the fan 71. [

In this case, the first communication portion 26 and the second communication portion 27 are disposed in a diagonal direction with respect to the cross section of the tub parallel to the ground on which the cabinet 1 is supported, and the heater 73 is disposed in the circulation duct And a portion extending along the longitudinal direction of the main body 7. The length of the flow path formed by the circulating duct 7 is made longer to secure a sufficient time for the air moving along the circulating duct 7 to be heated.

A part of the air supplied to the heater 73 is supplied through the intake duct 81 and a part of the hot air supplied to the tub 2 is exhausted through the exhaust duct 83 to the tub 2).

It is preferable that the intake duct 81 is provided on the flow path through which the air in the tub 2 flows into the fan 71. This allows the air circulation inside the tub 2 and the air outside the tub 2 to be circulated through the circulation duct 71 by only the fan 71 provided in the circulation flow path 71 without providing the air intake duct 81 with a separate air introduction means For example.

2 shows an example in which the air in the outside of the tub 2 is introduced into the circulating duct 7 through the first communication part 26 by the intake duct 81. [ In this case, when the fan 71 rotates, a negative pressure is formed in the first communication part 26, so that the air inside the tub 2 and the air outside the tub 2 flow into the circulating duct 7 will be.

3, the intake duct 81 provided in the present invention does not require a separate control means (valve or the like) for controlling the opening and closing of the intake duct 81. That is, the intake duct 81 provided in the present invention may be provided so as to be always kept open.

The intake duct 81 may include a communication portion 811 communicating with the first communication portion 26 and an extension portion 813 extending from the communication portion toward the circulation duct 7. It is preferable that the extension portion 813 extends a predetermined length along the height direction of the tub 2 in the communication portion 811 (the extension portion 813 is extended from the communication portion 811 to the circulation duct 7 It is preferable to extend it. The bubbles caused by the detergent during the washing of the laundry are prevented from being discharged to the outside of the tub 2 through the intake duct 81.

Further, the intake duct 81 may further include a filter F2 for filtering the air introduced into the extension 813. The filter F2 is provided in the circulation duct 7 and the extension 813 And can be fixed to the filter F2. That is, one end of the intake duct 81 of the present invention is fixed to the tub 2, and the other end thereof is fixed to the circulating duct 7.

This is a possible feature because the circulating duct 7 is fixed to the upper circumferential surface of the tub 2. Since the circulating duct 7 and the tub 2 will have almost the same vibration as viewed from the viewpoint of the vibration system of the garment processing apparatus 100, the suction duct 81 is arranged between the tub 2 and the circulating duct 7 So that the durability of the intake duct 81 can be maintained.

If the circulating duct 7 is fixed to the cabinet 1 rather than fixed to the upper circumferential surface of the tub 2, the circulating duct 7 will vibrate separately from the vibration of the tub 2, It would be difficult to ensure the durability of the intake duct 81 without the vibration absorbing device of Fig.

The exhaust duct 83 may be provided at any position of the tub 2 so as to discharge a part of the air introduced into the tub 2 through the circulating duct 7 to the outside of the tub.

1 shows an example in which the exhaust duct 83 is provided in the third communication part 28 provided on the upper circumferential surface of the tub 2. As shown in FIG. When air is supplied into the tub 2 by the fan 71, since the inside of the tub 2 is in a positive pressure state, a part of the air in the tub 2 flows through the exhaust duct 83 into the atmospheric- 2 and the rest of the air in the tub 2 will move to the circulating duct 7 through the first communication part 26 in a negative pressure state.

The sectional area of the exhaust duct 83 is set such that the sectional area of the exhaust duct 83 is smaller than the sectional area of the first communicating portion 26 (or the sectional area of the circulating duct 83) Is smaller than the cross-sectional area of the cross section.

On the other hand, the flow amount (exhaust amount) that can be exhausted by the exhaust duct 83 and the flow amount (intake amount) that can be sucked by the intake duct 81 to maintain the flow rate of the air supplied into the tub 2 are set to be the same or similar .

The exhaust duct 83 may be provided to communicate the inside of the tub 2 and the outside of the cabinet 1 to guide the air introduced into the exhaust duct 83 to the outside of the cabinet 1, And is connected to a drainage unit 6 provided to discharge water.

Since the air discharged through the exhaust duct 83 is highly humid air, if the exhaust duct 83 is provided to directly communicate with the outside of the cabinet 1, the air discharged from the exhaust duct 83 is condensed on the indoor wall Because it can cause problems.

Since the drainage unit 6 for discharging the washing water in the tub 2 to the outside of the cabinet 1 is provided in the clothes processing apparatus 100 of the present invention, if the exhaust duct 83 is connected to the drainage unit, Can be solved.

In this case, it is preferable that a connection point between the exhaust duct 83 and the drainage section 6 is further provided with a flow path switching section 9 for controlling the opening and closing of the exhaust duct and the drainage section 6. The air discharged through the exhaust duct 83 is prevented from being re-introduced into the tub 2 and the water discharged through the drainage unit 6 is prevented from being reintroduced into the tub 2. [

The drainage unit 6 provided in the present invention includes a first drainage passage 61 and a pump 63 for discharging washing water in the tub to the outside of the tub for discharging washing water, And a third drainage flow path 67 for guiding the water introduced into the flow path switching part 9 to an outdoor communication part (not shown) such as a sewer.

The flow path switching portion 9 provided at the connection point between the exhaust duct 83 and the drain portion 6 is preferably provided at a position higher than the maximum water level H set in the tub 3 (see FIG. 6).

The conventional garment disposal apparatus has a structure for preventing the water from being completely discharged from the third drainage duct to prevent the odor from being introduced into the clothes processing apparatus through the oil passage connected to the outdoor communication section as the third drainage passage 67 (Hereinafter referred to as " water trap ").

The air in the tub 2 can not be discharged to the outside of the tub 2 through the exhaust duct 83 when the laundry is dried when the drain duct 83 provided in the present invention is connected to the drain portion provided with the water trap . Therefore, when connecting the exhaust duct 83 to the drainage portion of the conventional clothes processing apparatus, the control unit must discharge the air with the pressure capable of removing the water trap through the control of the rotation speed of the fan.

However, when the flow path switching unit 9 is provided at a position higher than the maximum water level set in the tub 3 as in the present invention, since the exhaust duct 83 plays a role of preventing a siphon phenomenon, (Second drainage flow path) between the flow path switching portion 9 and the pump 63 to prevent the offensive odor from flowing into the tub 2.

Since the air introduced into the exhaust duct 83 can be discharged to the outside of the tub through the flow path switching unit 9 and the third drainage flow path 67, the rotation speed control of the fan 71 for removing the water trap Is unnecessary.

Also, the above-described structure can prevent the washing water from being discharged to the outside of the tub 2 through the drainage part 6 even if the washing water is supplied to the highest level set in the tub 2. [

The flow path switching unit 9 provided in the present invention may be provided as shown in FIG.

The flow path switching unit 9 includes a switching unit body 91 provided at a connection point between the exhaust duct 83 and the second drainage flow path 65 and a duct connecting pipe 91 connecting the exhaust duct 83 and the switching unit body 91. [ And a drain pipe 97 connecting the third drainage passage 67 and the switching unit body 91 to the first drainage passage 93, the second drainage passage 65 to the switching unit body 91, .

The duct connecting pipe 93 and the flow path connecting pipe 95 are provided to face each other while the duct connecting pipe 93 is provided on the upper part of the switching part body 91 and the flow path connecting pipe 95 is connected to the switching part body 91, As shown in FIG.

In this case, a switching valve 99 for opening and closing the duct connecting pipe 93 is provided in the switching unit body 91. The switching valve 99 includes a valve body 991 for opening and closing the duct connecting pipe 93 and a valve rotating shaft 993 for rotatably fixing the valve body 991 to the switching part body 91.

The valve body 991 maintains the state in which the duct connecting pipe 93 is opened by dead weight. However, when the washing water flows into the switching body 91 through the second drainage passage 65, And closes the connection pipe 93.

If the flow path switching unit 9 is provided only by the above-described structure, the washing water discharged from the tub can be prevented from flowing into the tub 2 through the duct connecting pipe 93, There is a problem that it is not possible to exclude the possibility of being supplied again to the tub 2 through the coupling pipe 95.

As described above, since the water trap is generated in the second drainage passage 65, it is possible to prevent the air discharged through the exhaust duct 83 from being re-introduced into the tub 2, If there is no discharge of water, the water trap may not be formed in the second drainage passage 65.

Therefore, the flow path switching unit 9 provided in the present invention may further include a flow path valve 951 for opening and closing the flow path connecting pipe 95. The flow path valve 951 may be provided as a check valve to open the flow path connection pipe 95 only when the wash water flows into the switching part body 91 through the second drainage flow path 65.

1 and 2, a clothes processing apparatus 100 according to the present invention includes a water supply unit 4 for supplying water required for washing to the tub 2, a detergent supply unit (not shown) for supplying detergent to the tub 2 5).

The water supply unit 4 includes a water supply passage for connecting a water supply source (not shown) provided outside the clothes processing apparatus 100 to the tub 2 and a water supply valve 41 (not shown) for opening and closing the water supply passage by a control unit ).

The detergent supply unit 5 may include a detergent storage unit 53 storing the detergent and a tub supply pipe 55 connecting the detergent storage unit 53 and the tub 2, And may be provided in any form as long as it can supply water to the detergent storage unit 53. In this case, the control unit (not shown) can supply the detergent stored in the detergent storage unit 53 and the water required for washing to the tub 2 by simply opening the water supply valve 41.

Meanwhile, the detergent storage unit 53 may be detachably attached to the front panel 11. The detergent supply unit 5 is further provided with a body 51 for supporting the detergent storage unit 53 so that the detergent storage unit 53 can be taken out from the front panel 11, And a storage unit through hole 15 through which the storage unit 53 is drawn out.

In this case, the inside of the detergent storage unit 53 should communicate with the body 51, and the tub supply pipe 55 should be provided to communicate the inside of the tub 51 with the inside of the tub 2.

The control section (not shown) can control the water supply section 4 (to improve the drying efficiency) so as to supply water required for cooling the tub 2 (air condensation inside the tub) to the tub 2. [

However, since the humid air in the tub 2 can be condensed in the detergent supply unit 5 and the laundry stored in the drum 3 can be wetted by supplying water to the tub 2 during drying of the laundry, The inventive clothing processing apparatus 100 may further include a water supply guider 25 for communicating the tub supply pipe 55 and the tub 2. [

The water supply guider 25 provided in the present invention forms a water trap (always reserving a predetermined amount of water to prevent the tub and the detergent supply portion from communicating with each other) so that the air inside the tub 2 flows into the detergent supply portion 5 And the water supplied to the tub 2 through the water supply unit 5 is moved to the bottom surface of the tub 3 along the inner circumferential surface of the tub 2 to prevent the laundry in the drum 3 from being wetted with water .

As shown in FIG. 5, the water supply guider 25 may be provided in the fourth communicating portion 29 provided on the upper circumferential surface of the tub 3.

The fourth communication part 29 may be a tube protruding from the circumferential surface of the tub as shown in the drawing, or may be provided with a hole penetrating the circumferential surface of the tub.

The water supply guider 29 includes a trap body 251 located in the fourth communicating portion 29 and providing a space for storing water, a gap between the circumferential surface of the trap body 251 and the inner circumferential surface of the fourth communicating portion 29, And a guide pipe 255 which is fixed to the fourth communication part 29 and guides the water supplied through the tub supply pipe 55 to the inside of the trap body 251.

The guide pipe 255 is provided along the circumferential surface of the guide pipe body 255a for guiding the water to the trap body 251 and the guide pipe body 255a is fixed to the fourth connection pipe 29 And a flange 255b.

The guide tube body 255a has a diameter such that the outer circumferential surface thereof is spaced apart from the inner circumferential surface of the trap body 251 by a predetermined distance and the lower surface of the guide tube body 255a through which the water is discharged is disposed on the bottom surface of the trap body 251 As shown in FIG.

The flange 255b should be provided so as to close the space between the outer circumferential surface of the guide tube body 255a and the inner circumferential surface of the fourth communicating portion 29. As shown in Figure 5, As shown in FIG.

The water supplied to the detergent storage unit 53 through the water supply channel 43 is supplied to the trap body 251 through the tub supply pipe 55 and the guide pipe body 255a and supplied to the trap body 251 The water flows into the tub 2 through the space between the inner circumferential surface of the trap body 251 and the outer circumferential surface of the guide tube body 255a and the space between the outer circumferential surface of the trap body 251 and the inner circumferential surface of the fourth communicating portion 29.

A certain amount of water is always stored in the trap body 251 and the lower surface of the guide pipe body 255a (the surface not provided with the flange) is kept in a state of being submerged in the water stored in the trap body 251, 2) can not be supplied to the detergent supply part (5).

The water supply guider 25 described above is disposed at a position spaced apart from the vertical line X passing the rotation center C1 of the drum 3 along the width direction Y of the tub 2 by a predetermined distance, The washing water stored in the drum 3 can be prevented from being wetted with water even when water is supplied into the tub 2 during drying.

The water supply guider 25 is positioned between the vertical line X1 contacting the circumferential surface of the drum 3 and the vertical line X2 contacting the circumferential surface of the tub along the height direction of the tub 2, 29, the above-mentioned effect will be maximized.

On the other hand, if it is difficult to provide the water supply guider 25 at the above-described position, the above-mentioned effect can be achieved by providing the supply flow path provided in the water supply guider 25 at the above-mentioned position.

5 (b), a plurality of fixing plates 253 for fixing the trap body 251 to the fourth communication portion 29 are provided along the circumferential surface of the trap body 251, The space provided between the other fixed plate 253 and the other fixed plate 253 serves as a flow path for introducing the water of the trap body 251 into the tub 2. [

Therefore, a part of the space provided between one fixing plate and the other fixing plate is constituted by the closing surface 259 and the remaining space is formed by the opening 257, and the opening 257 is formed by the circle of the drum 3 It is possible to prevent the laundry from being wet by the water supplied to the tub 2 during the drying if the vertical line X1 contacting the main surface and the vertical line X2 contacting the circumferential surface of the tub 2 are provided.

That is, the opening face 257 passes through the center C2 of the fourth communication portion 29 and is spaced away from the vertical line X passing the rotation center C1 of the drum on the basis of a straight line Z parallel to the longitudinal direction of the tub Direction or arc-like shape positioned in the direction of the arrow.

The length of the opening 257 may be set to be 1/4 or more and less than 1/2 of the circumferential length of the trap body 251. In this case, From the viewpoint of the angle, the arc-shaped opening 257 may be provided so that the central angle is 45 degrees or more and less than 180 degrees with respect to the center C2 of the fourth communicating portion 29.

The shape and positional characteristics of the open side 257 described above are intended not only to prevent the laundry from getting wet during water supply during drying, but also to minimize an increase in water supply time during washing.

Referring to FIG. 2, the drying system (the process of drying laundry by supplying heated air to the laundry) implemented by the above-described clothes processing apparatus 100 of the present invention is as follows.

The air in the tub 2 flows into the circulating duct 7 through the first communicating portion 26 and the air introduced into the circulating duct 71 is heated by the heater 73 And then supplied to the tub 2 through the second communication portion 27. [ The air supplied to the tub 2 is heat-exchanged with the laundry stored in the drum 3 and then moved toward the first communication part 26.

The tub 2 exchanges heat with the air inside the cabinet 1 (or air introduced into the cabinet through the cabinet through holes 19 and the like) so that the temperature of the surface of the tub 2 is lower than the center of the tub 2 . Therefore, since the air after being discharged from the drum 3 is cooled in the process of moving toward the first communication portion 26, a part of the moisture contained in the air condenses on the inner circumferential surface of the tub 2.

Therefore, the tub 2, the circulating duct 7, the fan 71, and the heater 73 provided in the present invention are capable of dehumidifying the air discharged from the tub, heating the dehumidified air, (A first heat exchange passage and a heating section).

Meanwhile, a part of the air having undergone the heat exchange with the laundry is discharged to the outside of the tub 2 through the exhaust duct 83, and the remaining air is recovered to the circulating duct 7 through the first communication part 26, Is mixed with the air outside the tub (2) flowing through the intake duct (81).

The air discharged from the drum 3 is dehumidified by heat exchange with the tub 2 while moving to the first communicating part 26, but the air recovered by the circulating duct 7 according to the amount of laundry (amount of laundry stored in the drum) It may be difficult to maintain a state in which a sufficient amount of moisture is removed. The exhaust duct 83 and the intake duct 81 are means for solving such a problem.

That is, according to the present invention, a part of the air introduced into the first communication part 26 from the tub 2 is discharged to the outside of the cabinet 1 through the exhaust duct 83, (The air outside the tub) supplied through the intake duct 81 is mixed with the air introduced into the circulating duct 7 from the tub 2 to adjust the humidity of the air supplied to the heater 73 To a desired level.

The intake duct 81, the fan 71, the heater 73 and the exhaust duct 83 provided in the present invention not only heats the air outside the tub to supply the air to the tub, but also a part of the air that has undergone heat exchange with the laundry in the tub (Second heat exchanging passage and heating section) for discharging the exhaust gas to the outside of the tub is formed.

Accordingly, the present invention prevents drying efficiency from being lowered regardless of the amount of laundry or the type of laundry (regardless of the humidity of the air discharged from the tub) through the drying system in which the circulation type drying system and the exhaust type drying system are combined can do.

It is preferable that the exhaust duct 83 and the intake duct 81 are kept open during the drying process and the amount of air flowing into the circulating duct 7 through the intake duct 81 (Amount of intake air) discharged to the outside of the tub 2 through the exhaust duct 83 are substantially equal to each other.

On the other hand, if the intake efficiency and the exhaust amount are the same, the drying efficiency is the highest, but if it is difficult to match the intake amount and the exhaust amount, it is preferable that the exhaust amount is set to be larger than the intake amount.

If the intake amount is larger than the exhaust amount, the amount of hot air supplied to the tub 2 increases and the amount of hot air supplied to the tub increases, which means that the amount of air to be dehumidified by the tub 2 is increased. Therefore, if the intake duct and the exhaust duct are provided so that the intake air amount is larger than the exhaust amount, the drying efficiency may be lowered when the laundry is dried without using the cooling water, so that the exhaust amount is preferably set to be larger than the intake amount.

Although the drying system described above has a risk of increasing the drying time depending on the amount of the laundry, the present invention solves the problem by controlling the water supply unit 4. That is, in the drying system embodying the present invention, the above-described risk can be solved by controlling the water supply unit 4 such that a control unit (not shown) supplies water to the inner circumferential surface of the tub 2 during drying of the laundry.

When the water for cooling the inner circumferential surface of the tub 2 is supplied to the tub 2 through the water supply portion 4 during the drying operation, the inner circumferential surface of the tub 2 is rapidly cooled, so that the humidity of the air flowing into the circulating duct 7 is kept low And the degree of drying of the air flowing into the circulating duct is kept high).

The water supplied to the tub 2 through the water supply unit 4 is moved to the drainage unit 6 along the inner circumferential surface of the tub by the water supply guider 25 so that the laundry stored in the drum 3 is wetted with water, The risk of becoming very low.

Meanwhile, it is preferable that the process of supplying water to the tub 2 through the water supply unit 4 for saving water is performed according to the user's selection. To this end, the control panel 17 is further provided with a first mode selection unit 171 for supplying laundry to the tub and drying the laundry, and a second mode selection unit 173 for drying the laundry without supplying water to the tub (See Fig. 1 (b)).

Meanwhile, the above-described clothes processing apparatus 100 of the present invention may be configured as shown in FIG.

The clothes processing apparatus 100 shown in Fig. 6 is the same as the structure of the clothes processing apparatus shown in Figs. 1 to 5 except for the connection relationship between the circulating duct 7, the intake duct 81 and the exhaust duct 83 Do.

That is, the tub 2 provided in the present embodiment receives the air outside the tub 2 (the inside of the cabinet or the outside of the cabinet) through the intake duct 81 and the exhaust gas from the tub 2 And guides a part of the air inside the tub 2 to the intake duct 81 through the circulating duct 7 (connecting duct).

The fan 71 and the heater 73 are provided inside the intake duct 81 and the circulating duct 7 is connected to the flow path of the intake duct 81 for guiding air to the fan 71 And the inlet of the intake duct).

The circulating type drying system is also formed by the first heat exchanging flow path and the heating portions 71 and 73. The first heat exchanging flow path is formed by the tub 2, the circulating duct 7, the connecting duct, And a part of the flow path of the intake duct 81 for guiding the discharged air to the tub 2.

The exhaust drying system of the present embodiment is formed by the second heat exchange passage and the heating portions 71 and 73. The second heat exchange passage is constituted by the intake duct 81, the tub 2 and the exhaust duct 83 do.

Therefore, this embodiment can also achieve the same effects as those of the embodiment described with reference to FIGS.

7 shows a control method of the clothes processing apparatus 100. The control method of the clothes processing apparatus of the present invention includes a drying step S30 for supplying heated air to the tub 2, And a motion execution step S50 for rotating the drum 3 according to a predetermined motion.

The drying step S30 is a circulation process S31 for discharging the air inside the tub 2 to the outside of the tub 2 and supplying the air to the outside of the tub 2, An intake process S35 for mixing the air outside the tub into the air circulated through the circulation process, and a heating process S37 for heating the air supplied to the tub 2.

The circulation process S31 is a process in which the air in the tub 2 flows along the circulating duct 7 by the operation of the fan 71 and starts with the operation of the fan 71. [ In the circulation process S31, not all of the air in the tub 2 flows into the circulating duct 7. That is, a part of the air inside the tub 2 is re-supplied to the tub 2 through the circulation process S31, but a part of the air inside the tub is discharged to the outside of the tub through the exhaust process S33.

The air discharged from the tub 2 through the exhausting process S33 flows through the duct switching portion 9 and the third drainage flow path 67 to the clothes processing device (100).

The intake process S35 is performed through the intake duct 81 and the intake duct 81 is provided in the first communication section 26 connecting the circulation duct 7 and the tub 2, When the circulation process S31 is started by the operation, the intake process S35 is also started.

The heating process S37 is a process in which the heater 73 heats the air mixed in the circulation duct 7 through the circulation process S31 and the intake process S35.

In the drying step (S30) described above, the present invention can be applied to the supply of heated air, the dehumidification of air that has undergone heat exchange with the laundry, the reheating of a part of the air discharged from the tub, the exhaust of a part of the air discharged from the tub, Can be supplied to the laundry.

The motion execution step S50 is executed during the course of the drying step S30. The motion execution step S50 may be performed to execute only one of the first motion and the second motion, and the execution of the first motion (S53) And the execution step S51 may proceed according to a predetermined order.

In the first motion executing step S53, the drum is rotated in accordance with the first motion. In the first motion, the drum 3 is rotated in either the clockwise direction or the counterclockwise direction, (Not falling) by repeating that the hot air supplied to the tub 2 and the laundry are heat-exchanged efficiently.

The first motion execution step S53 includes a step S531 of rotating the drum at a first rotation speed (reference rotation speed) at which the centrifugal force induced in the laundry by the rotation of the drum 3 is greater than the self weight of the laundry, (S533) of rotating the drum 3 at a second rotational speed set to a rotational speed higher than the first rotational speed (S533), and repeating the two processes S531 and S533 for a predetermined number of times or a predetermined time .

The drum 3 rotates only in the same direction in the process of rotating the drum at the first rotational speed (S531) and the process of rotating the drum at the drum (S533), and the first rotational speed and the second rotational speed are Since the laundry is rotated together with the drum 3, the laundry in the first motion executing step (S53) will see the movement of the form shown in FIG.

That is, when the drum 3 rotates at the first rotational speed, the laundry L is kept in a state of being in close contact with the inner circumferential surface of the drum 3 for a predetermined period of time The laundry L is kept in close contact with the inner circumferential surface of the drum 3 for a certain period of time but is more closely attached to the inner circumferential surface of the drum 3 as compared with the case where the drum rotates at the first rotational speed (a)).

The centrifugal force induced in the laundry is larger when the drum rotates at the second rotation speed than when the drum rotates at the first rotation speed because the second rotation speed is larger than the first rotation speed.

The first rotation speed and the second rotation speed are set so that the laundry L can be rotated together with the drum in close contact with the inner peripheral surface of the drum to secure a space for moving hot air inside the drum 3. [ The surface area of the laundry that can contact the hot air supplied to the tub by the first motion is maximized, so that the heat exchange efficiency between the hot air supplied to the tub 2 and the laundry will be enhanced.

On the other hand, the first rotation speed and the second rotation speed are set to be different from each other so that the through holes 33 provided in the drum 3 are opened and closed by the laundry. That is, while the drum is rotating, the hot air is held in the drum 3, and the air inside the drum 3 is discharged to the tub 2 while the drum rotates with the first rotation speed .

Some of the hot air introduced into the drum 3 is discharged to the tub 3 after the heat exchange with the laundry is completed, but a part of the air introduced into the drum 3 is discharged through the through hole 33 to the tub 2 without heat exchange with the laundry. Therefore, the conventional clothes processing apparatus has a problem in that the heat exchange efficiency between the hot air and the laundry is low and the energy consumption is increased.

The present invention can solve the above-mentioned problem of the conventional clothes processing apparatus by controlling the number of revolutions of the drum.

When the drum 3 is rotated by the second rotation speed, the laundry is brought into close contact with the inner circumferential surface of the drum 3 due to a large centrifugal force. Therefore, when the amount of the laundry is more than a predetermined amount, When the water channel drum rotates, it is possible to minimize the hot air in the drum 3 from escaping into the tub 2 through the through holes 33.

When the drum rotates at the first rotational speed, the laundry is kept in a state of being closely attached to the inner circumferential surface of the drum 3 by a relatively small centrifugal force, so that the hot air inside the drum 3 passes through the through hole 33 to the tub 2 Can be discharged.

It is preferable that the time set in the step S533 of rotating the second rotating speed drum to increase the heat exchange efficiency between the laundry and the hot air is longer than the time set in the step S531 of rotating the drum with the first rotating speed Do.

However, since the condensing efficiency of the air moving to the circulating duct 7 may vary depending on the time period during which the hot air is discharged from the drum 3 to the tub 2 (the amount of hot air discharged to the tub) And the time for rotating the drum by the second rotation speed are set at a constant ratio. 8 shows an example in which the time for rotating the drum at the first rotational speed and the time ratio for rotating the drum at the second rotational speed are 1: 3.

Meanwhile, the second motion execution process S51 is a process of rotating the drum according to the second motion, and the second motion repeats the rotation of the drum 3 and the rotation of the drum, (The motion to increase the stirring efficiency of the laundry and the heat exchange efficiency) from the upper portion of the horizontal line Y passing through the lower portion C1 to the lower portion of the horizontal line Y. [

7, the second motion executing step S51 includes a step of rotating the drum 3 at the third rotational speed (S511), a step of rotating the drum 3 before the drum 3 completes one revolution (S513), and repeating the two processes S511 and S513 for a preset number of times or a predetermined time period (S515).

The third rotational speed is set so that the centrifugal force induced in the laundry by the rotation of the drum 3 is larger than the dead weight of the laundry, and the third rotational speed is set to any one of the first rotational speed or the second rotational speed As shown in FIG.

The process of stopping the rotation of the drum (S513) is started when the laundry is raised by more than half (h) of the height of the drum, so that the laundry exhibits the movement of the shape shown in FIG. 9 will be.

The laundry L is rotated with the drum 3 in close contact with the inner peripheral surface of the drum 3 (Fig. 9 (a)), and the laundry L is rotated 9 (a) and 9 (b), when the drum is rotated by half (h) or more of the height of the drum (S513), the laundry drops downward from the upper portion of the horizontal line Y toward the inner peripheral surface of the drum 3 b)).

The surface area of the laundry exposed to the hot air supplied to the drum 3 by the second motion increases and when the laundry L hits the inner circumferential surface of the drum 3, the moisture contained in the laundry is easily separated. It is possible to increase heat exchange efficiency between hot air and laundry (increase in drying efficiency).

In addition, the second motion prevents the laundry from tangling to each other in the drum 3 because the laundry is provided so that the laundry repeatedly rises and drops in the drum 3. [

In order to maximize the above-described effect, the process of stopping the rotation of the drum (S513) is performed by rotating the drum 3 in the direction opposite to the direction of rotation of the drum 3 3). ≪ / RTI > This is to provide a greater impact force on laundry.

The process of stopping the rotation of the drum (S513) is preferably performed when the laundry is rotated at an angle of 90 degrees or more and less than 180 degrees based on the minimum trajectory B of the trajectory of the drum 3.

The above-described second motion may be set so that the drum 3 is rotated in either the clockwise direction or the counterclockwise direction as shown in Fig. 9 (c), and as shown in Fig. 9 (d) It may be set to alternately perform the clockwise rotation and the counterclockwise rotation of the drum 3 as well.

Also, the process of rotating the drum by the third rotation speed (S511) and the process of temporarily stopping the rotation of the drum (S513) are repeated for a preset time or a predetermined number of times (S515) It can be set to gradually increase every time the motion is repeated.

That is, the third rotation number set in the second motion, which is executed first when the second motion is executed a plurality of times, may be set smaller than the third rotation number set in the subsequent second motion (see FIG.

Further, the third rotation speed set in the drum rotation process (S511) may be set to increase each time the second motion is repeated, and to decrease after the second number of times of the second motion is repeated.

If the third rotation speed is gradually increased each time the execution of the second motion is repeated, the moisture contained in the laundry may be easily removed.

Meanwhile, it is preferable that the process of executing the second motion (S51) is executed before the process of executing the first motion (S53), which prevents the laundry from being entangled in the drum 3 through the second motion So that the laundry 3 can be uniformly dispersed on the inner circumferential surface of the drum when the first motion is executed.

It is preferable that the time set in the step S53 of executing the first motion is set longer than the time set in the step S51 of executing the second motion since the thermal energy supplied to the drum 3 is supplied to the drum 3) to increase the heat exchange rate between the laundry and the hot air.

The control method of the present invention may include only the above-described drying step (S30) and the motion executing step (S50) but may further include the cooling water supplying step (S70) shown in FIG. The cooling water supply step S70 is a step of supplying water to the inner circumferential surface of the tub 2 during the motion execution step S50 to cool the inner circumferential surface of the tub 2 that performs heat exchange with the air discharged from the drum 3. [

In the present invention, it is preferable that the cooling water supply step (S70) is performed according to the user's selection. To this end, the present invention includes a mode selection step of setting whether or not the cooling water supply step (S70) (S10).

The mode selection step S10 may include a step of the user inputting a control command through the first mode selection unit 171 and the second mode selection unit 173 provided in the control panel 17. [

The first mode selection unit 171 is a means for selecting a control method (so-called 'turbo drying mode') for executing the cooling water supply step S70 during the progress of the motion execution step S50, and the second mode selection unit 173 are means for selecting a control method (also called 'wind drying mode') for proceeding with the motion execution step S50 without executing the cooling water supply step S70.

The mode selection step S10 is a step in which a control unit (not shown) selects a first mode in which the cooling water supply step S70 is provided irrespective of the user's preference, according to the amount of laundry stored in the drum 3 It can be done.

In either case, the control method of the present invention judges whether or not the first mode is selected together with the start of the drying step (S30) (S40).

When the first mode is not selected (the second mode is selected), the control method of the present invention sequentially executes only the second motion execution step S51 and the first motion execution step S53. However, when the first mode is selected, the control method of the present invention performs the cooling water supply step (S70) while the first motion is executed (S53).

At the beginning of the drying step (S30), the heat exchange rate between the laundry and hot air is low. The degree of drying of the laundry tends to increase sharply from the point at which the laundry reaches a certain temperature, until the laundry reaches a certain temperature.

This is because the temperature of the laundry must be higher than a certain temperature in order for the moisture contained in the laundry to evaporate, and the humidity of the air discharged from the drum 3 increases toward the latter half of the drying step (S30).

Therefore, when a certain time elapses after the start of the drying step S30 (start after the execution of the second motion is finished) than when the second motion proceeding with the start of the drying step S30 is executed (S51) It is more advantageous to dry the laundry than to cool the tub in the execution of the first motion (S53).

Further, it is preferable that the cooling water supply step (S70) is performed during the step (S533) of rotating the drum at the second rotation speed among the steps provided in the first motion.

It is intended to prevent the laundry in the drum 3 from wetting even if the water supplied to the tub 2 through the water supply unit 4 is accidentally moved toward the drum 3. (If the number of revolutions of the drum is high, Will move away from the drum).

The control method of the present invention determines whether the drying time of the drying step S30 and the motion executing step S50 has exceeded the drying time set in the drying time setting step S20 in step S80, The execution step S50 ends.

The drying time setting step S20 is preferably performed before the start of the drying step S30. In the drying time setting step S20, a controller (not shown) may be provided to set a drying time based on the amount of laundry , And may set the time inputted by the user through the control panel to the drying time.

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
